Black Diamond Sonar Backpack

Featuring our reACTIV suspension and a spacious interior capable of swallowing a full day's worth of gear, the 26-liter Black Diamond Sonar pack is ready for summit scrambles, loop hikes and any other on- or off-trail day of adventure. The Sonar's high-flow OpenAir backpanel, shoulder straps and waistbelt keep your back cool and well ventilated during hot, sunny days. We designed the Sonar with a slew of organizer pockets, including a fleece-lined pocket for your phone or MP3 player and a raincover pocket (raincover not included) if the weather gets foul.
